The sky was cloudless and starry. I looked up from my driveway to see what I first thought was a night bird, but as my eyes followed it, I could see it was a horizontal triangle with three lights. Because the night sky was filled with stars, I could see the shape of the object as it blocked the stars’ light. The triangle appeared to be about 200 feet up, moving easterly in an almost-straight line, wobbling slightly, not always quite level. It moved at the pace of a soaring bird, coasting through the air. It seemed to be about five feet wide. Three round lights were evenly spaced in its corners, the same color as the stars, pale bluish-white, with indistinct edges. The triangle itself appeared to be grayish, though that may be only because it was against the dark sky. I noticed in particular that it made no sound.
